A perfect fit for your Atari Mega ST or Mega STE
The ACSI2STM is an open-source hard drive emulator that allows Atari ST computers to utilize SD cards as storage devices. Traditionally, this device connects externally via the ACSI port, which can lead to clutter and potential wear on connectors.
To address this, we’ve developed two new riser boards that enable the internal installation of the ACSI2STM device within Atari Mega ST and Mega STE computers. This enhancement allows users to integrate the ACSI2STM seamlessly into their systems, eliminating the need for external connections and external powering, and preserving the original aesthetics of the computer.
Benefits of Internal Installation:
- Internal Power Supply: No more wires to power your external device.
- Preserved Aesthetics: Maintains the original look of your Atari by keeping the ACSI2STM device concealed within the case.
- Reduced Wear: Minimizes wear on external ports and connectors by eliminating the need for constant plugging and unplugging.
- Space Efficiency: Frees up workspace by removing external devices and cables.
Key Features of the Riser Boards:
- Tailored Design: Specifically designed to fit the internal architecture of the Atari Mega ST and Mega STE models.
- Easy Installation: Clear instructions, making the upgrade process straightforward for users with basic technical skills.
- Secure Mounting: Ensures the ACSI2STM device is firmly seated, preventing movement and potential damage.
By utilizing these riser boards, you can enjoy the modern storage capabilities of the ACSI2STM while keeping your Atari setup clean and authentic. This solution offers a harmonious blend of vintage computing and contemporary convenience, enhancing your overall user experience.

- Pre-soldered 20-pin female connector.
- Pre-soldered USB-A power-only female connector.
- USB-A to USB-C cable (length varies between 10 cm and 15 cm, depending on availability).
Kit Contents for Mega ST:
- Riser board specifically designed for Mega ST.
- Pre-soldered 24-pin female connector.
- Pre-soldered 20-pin female connector.
- Pre-soldered USB-A power-only female connector.
- Two pre-soldered male pins for 5V power connection.
- 20 cm female-to-female Dupont red connector.
- USB-A to USB-C cable (length varies between 10 cm and 15 cm, depending on availability).
Important: The riser boards connect to the ACSI2STM Compact model using the 20-pin connector located at the back of the device, commonly referred to as the “Satan Disk” connector. It is essential that your ACSI2STM unit includes this connector. All ACSI2STM models produced by SidecarTridge come with this connector, though it may not be pre-soldered. Compatibility with devices from other manufacturers cannot be guaranteed.
Frequently Asked Questions
What is the purpose of the ACSI2STM internal riser boards?
The riser boards are designed to facilitate the internal installation of the ACSI2STM hard drive emulator within Atari Mega ST and Mega STE computers. This setup eliminates the need for external connections and power supplies, preserving the original aesthetics and reducing wear on external ports.
Why are there separate riser boards for the Mega ST and Mega STE models?
There are two distinct riser boards tailored specifically for the Mega ST and Mega STE models, respectively. Each is designed to fit the internal architecture of its corresponding model. In the case of the Mega ST, the riser board includes additional Dupont wire connector to power the ACSI2STM device.
How do I install the riser board and ACSI2STM device internally?
Please read the Quickstar to learn how to install the riser board and ACSI2STM device internally in your Atari Mega ST or Mega STE computer.
How do I power the ACSI2STM device when installed internally?**
The riser boards are designed to provide power to the ACSI2STM device internally, eliminating the need for external power sources. The included USB-A to USB-C cable connects the riser board’s USB-A power-only female connector to the ACSI2STM’s USB-C port. The Mega ST riser board also includes two a female-to-female Dupont connector to power the ACSI2STM device from the Atari’s power supply.
###Â I bought the ACSI2STM Compact device to other manufacturer. Can I use the riser boards?
The riser boards are designed to work with the ACSI2STM Compact model with a 20-pin connector located at the back of the device. If you have an standard 20 pin connector, you should be able to use the riser boards. However, compatibility with devices from other manufacturers cannot be guaranteed. Use at your own risk.
###Â Can I use the riser boards with other ACSI2STM models?
The riser boards are designed to work with the ACSI2STM Compact model with a 20-pin connector located at the back of the device. I can’t guarantee compatibility with other ACSI2STM models. Use at your own risk.
Why don’t you ship to some European countries?
I’ve made the difficult decision to discontinue shipping to Austria, Bulgaria, Cyprus, Greece, Latvia, Lithuania, Luxembourg, Portugal, Romania, Slovakia, Spain and Sweden. This decision was not made lightly and is primarily due to the specific and significant costs associated with recycling packaging and electronics in these countries. Unfortunately, these costs are disproportionately high relative to the demand I’ve experienced, making it unsustainable for me to offer the products in these markets while adhering strictly to the legal requirements.
However, you can still find this and other products in various marketplaces like eBay, Tindie and others with a simple search.
